“…The highest frequency was detected in specimens from Birds´ Island, indicating that this species is a reliable indicator of pollution from organotin compounds, mostly arising from paint from boats (Paz-Villarraga et al, 2015). Moreover, females from Birds' Island have also the highest levels of imposex (Level 2), suggesting the female population of this species at this site could have a low reproductive capacity in the future (Fernández et al, 2002).…”

“…Some of those studies have linked the extent of the imposex level detected in specimens from Birds' Island to adverse effects such as low reproductive capacity or even complete sterility, affecting its health and survival capacity (Fernández et al, 2002). Although this is the first report for Cartagena, North of Colombia, imposex-related studies have also been documented for several species in other geographic locations in South America, including Brazil (Zeidan and Boehs, 2016;Fernández et al, 2002), Venezuela (Paz-Villarraga et al, 2015) and Ecuador (Castro et al, 2012).…”

Imposex is the development of male sexual characteristics caused by the toxic effects of some chemicals that acts as an endocrinal disruptor. Antifouling paints contain these chemicals. Cartagena lacks studies to indicate the extent of imposex in its coastal waters. The aim of this study was to determine the prevalence of imposex in the gastropod Stramonita haemastoma in Cartagena, Colombia. Specimens were collected during 2013 from locations of high and low influence of port activity. Morphometric measurements and the frequency of the occurrence of imposex were registered. The comparison among morphometric variables showed statistically significant differences between the two sites studied. Furthermore, the females of the S. haemastoma species presented an imposex frequency of 93.1% in Birds' Island, Cartagena Bay, compared to 31.8% in La Bocana. The relative penis size index or RPLI (10.145 and 3.231) and vas deferens sequence index or VDSI (2.83 and 1.16), showed possible contamination by organotin compounds in both places.Keywords: imposex, bioaccumulation, boat paint, organotin compounds, penis development, toxicity.

“…Pinochet et al 2009), a straightforward relationship is not always seen (i.e. Shim et al 1999;Paz-Villarraga et al 2015) since other factors such as BT sources and characteristics, organic matter composition, and biological activity of the sediment (Town and Filella 2002) also plays a role in this association.…”

The distribution of butyltins (BTs) and polycyclic aromatic hydrocarbons (PAHs) were studied in surface sediments to assess how relevant is Mar del Plata port (Argentina) as a source of contamination to the surrounding environments. Within the port, TBT concentrations ranged from 24.2 to 150 ng Sn g(-1) and PAHs (Σ16) from 180 to 17,094 ng g(-1). At the surrounding beaches, PAHs were detected at low concentrations and TBT concentrations reached 10.9 ng Sn g(-1). Although those low levels indicate that the Port might not be an important source of contamination to the surrounding beaches, the very low TOC content and the coarse grain size of the beaches sediments could explain the sedimentary levels. The results show a reduction in TBT levels in Mar del Plata port after national and international use restrictions of TBT-based antifouling paints.

“…In South America, imposex and TBT environmental levels (surface sediments and biota samples) have been detected in Argentina (Penchaszadeh et al 2001;Bigatti et al 2009;Penchaszadeh et al 2009;Arrighetti and Penchaszadeh 2010), Venezuela (Paz-Villarraga et al 2015), Ecuador (Castro et al 2012b), and Peru (Castro and Fillmann 2012). On the Brazilian coast, particularly in recent years, imposex associated to TBT has been reported in the southern (Castro et al 2012a), southeastern (Fernandez et al 2005;Quadros et al 2009;Costa et al 2009;Cardoso et al 2009;Borges et al 2013), and northeastern regions (Camillo et al 2004;Castro et al 2004;Castro et al 2007a, b;Fernandez et al 2007;Castro et al 2008;Lima-Verde et al 2010;Azevedo et al 2012).…”

Tributyltin (TBT) contamination is still recorded in the environment even after its ban in antifouling paints. Since most biomonitors of TBT contamination, through imposex evaluation, are hard-bottom gastropods, the identification of soft-bottom sentinels has become useful for regions where rocky shores and coral reefs are absent. Thus, an evaluation of Olivella minuta and Hastula cinerea as monitors of TBT contamination was performed in two sandy beaches located under influence area of São Sebastião harbor (São Paulo state, Brazil), where previous and simultaneous studies have reported environmental contamination by TBT. In addition, the imposex occurrence in H. cinerea was assessed in an area with low marine traffic (Una beach), also located in São Paulo State. A moderate imposex incidence in O. minuta was detected in Pernambuco (% I = 9.36, RPLI = 4.49 and RPLIstand = 4.27) and Barequeçaba (% I = 2.42, RPLI = 0.36 and RPLIstand = 0.81) beaches, indicating TBT contamination. In contrast, more severe levels of imposex were recorded for H. cinerea in Una beach (% I = 12.45) and mainly in Barequeçaba beach (% I = 98.92, RPLI = 26.65). Our results suggest that O. minuta and H. cinerea have good potential as biomonitors for TBT based on their wide geographical distribution, common occurrence in different coastal sediment habitats, easy collection, and association with TBT-contaminated sediments.
